I checked a few tube manuals and only Western Electric gives the pin diameters, except not for octal tubes. I don't have access to IEC 60067, so decided to measure a couple of tubes from the 1950s. Both a GE 6L6G and a National Union 6A5G have 2.33mm diameter pins. I don't have any Chinese tubes so I measured an EML 2A3 V4 with an octal base: 2.35mm.
